Question about 2007 Chevrolet Astro

Open Question

This is an intermittant problem. Over the past say 2 years the engine of my 1400 Corsa Utility cuts out above 4000 rpm (120km per hour in 5th gear). This usually happens after about 100km cruising at 120km per hour. The engine shudders and the service light comes on. There is no overheating, no stange sounds. If I then stop, switch off the engine and then re-start, the service light goes off and the car seems fine. The problem is the local dealership can't find the problem, because by the time I take the car to them, the problem has gone away. Any ideas?

SOURCE: grinding noise while driving.

Possible causes:

a) a brake disc shield is too close to the disc, and it's coming into contact in the circumstances you outline

b) pebbles stuck between the disc shield and the disk

c) dried out wheel bearings

d) worn Universal Joints in the drive shafts

e) worn A/C pump

f) worn alternator

g) worn water pump

Is the noise still present above 15 miles an hour and past 1500 rpm when the clutch is disengaged (i.e. gearbox in neutral?). The answer to this question may help you to pinpoint the source. I know it's stating the obvious but the fact that you're hearing a grinding sound means it's caused by something that is moving relative to something else. Again this should help narrow down the cause.

SOURCE: My 2007 veracruz has a shudder when starting in

Mine had a *bad*, but intermitent engine shudder (like it was running out of gas) between 30 and 40 mph. After 3 trips to the dealer, it finally did it in front of them. It's quite dramatic, so they admitted that I wasn't just bringing it in for fun and started guessing what was wrong. They found a TSB that recommended starting with one of the O2 sensors, which fixed it perfectly, immediately.

Sounds like yours isn't your engine - but I thought I should say something just in case.

SOURCE: WHEN IDLEING VEHICLE MISFIRES AND

The tok tok sound is probably a blown exhaust gasket. Replace the exhaust manifold gasket. As for the rough idle , replace the distributor cap, cap rotor, spark plugs and wires. With any luck this will take care of the misfire at idle and improve your gas mileage for a minimal cost for the repair.

What causes hesitation in 3rd, 4th and 5th gear?


I would suggest that you take your car to O'rielly's or one of the larger auto parts chain stores and have them connect the diagnostic reader to your car. It sounds to me as though you are experiencing something to do with the cars computer and the way it is reading it's sensors. They will do this for free and then tell you what the error codes mean, if any. If you do receive error codes, chances are that is your problem and you will then be aware of what it is and what it will cost to clear it up and not have some mechanic charging you for his time doing exploratory diagnostics and charging you an arm and a leg just to find out whats wrong.

My 1.8l Corsa Utility cuts out at exactly 4000 rpm while driving no matter what gear. Engine electronics, transmission electronics, immobilizer stays on constantly


Although I am not familiar with your particular engine, some have a "rev limiter" which can fail and cause your issue. Older cars had a rotor button in the distributor which would open the spark circuit when a certain speed is reached, but yours probably has and electronic limiter. Also, some ignition modules have a low speed and separate high speed module, which may have failed. May be best to let a dealer do the diagnostics, then fix the problem yourself once you know what it is.

My vw Golf 4 1998 model, engine 1.8 speed sensor is dead. now temporarily i would like to know if i have to drive 120km/h, what rpm do i have to drive at using the rpm meter?


roughly if you are doing 3000rpm you will be doing approx. 100 klms/hr or 60 mph at 120km/hr you would be around 3200rpms.; Remember this will be in o/drive or 5th

My 1999 ford expidition sounds like its shifting in overdrive when i reach about 40 miles per hour, the engine gets loud sounds a jet taking off.


You have it backwards

What you hear is engine noise from
higher rpm, because your trans is not
upshifting, as a result of your input on
the gas pedal

You need to have a trans or repair shop find out why
you have a delayed or no shift condition

When you get to 4th or 5th gear (overdrive) you also
get torque converter lock-up & things should get quieter

2009 Hyundai accent in 5th gear the RPM is 4000 is this normal? My speed is 115 Klm an hour


No, it is not. You should be around 2500 rpm at 115 Kilometers an hour. Even if you were in 4th it should only be around 3000 rpm. At 115 MPH you would be near the 4000 RPM. Your either running on 3 cylinders or your transmission is in trouble and needs repair.

Car has no power and has a rattling noise


RPM and speed do not match what I'd expect to see at 120. but that could be gear ratio being different than I'd expect. Most don't like to run at 4k. Most problems at that rpm is either plugs (experiment with different gap settings or change heat range one step colder or hotter) or can be coil related (work fine except when recovery time is shortened due to rpm). However, the weird noise may be due to a partially plugged catalytic converter. So, check that as well. If you have a knock sensor, test that too.

4000 rpm at 70 miles per hour


You should have another gear "5th" at 70mph your tacho should read about 2500 rpm.
Make sure you don't need to depress something or push the gear stick against a spring to select 5th.
Is there a gear layout on top of the gearstick knob, do you have 5th gear on there?
The highest gear ratio is a little over 1 to 1 so at 70 mph you would expect 3500 rpm, but, it is a little over 1 to 1 so it will be closer to 2500rpm.
